Shotaro Tatewaki knows that Sakurako Kujo isn't a normal person. After all, most young women have multiple interests revolving around things like work, fashion, and sports, but Sakurako is fixated on just one thing: bones.

While she already has a huge collection of them, mostly animal, she's always trying to gather more, especially those of the human variety. This can be quite a problem for Shotaro: especially since he and Sakurako have a positively unnatural aptitude for discovering dead bodies together.

Fortunately, Sakurako is a naturally brilliant detective who unearths the mystery of what happened to the owners of those bones, but it's up to Shotaro to make apologies for Sakurako's odd quirks and tendency to make off with the evidence.

It's a grave business that can leave him literally bone-tired, but for the wheels of justice to turn, there are always more skeletons to be bared and new secrets to be exhumed in BEAUTIFUL BONES -SAKURAKO'S INVESTIGATION-.
